Process for preparing 2-chloro-3-alkoxy-4-alkylsulfonyl-benzoic acids and esters |
abstract |
1-Halo-2-chloro-3-alkoxy-4-alkylsulfonylbenzene and 1-halo-2,3-dichloro-4-alkylsulfonylbenzene compounds were converted to compounds having hydroxycarbonyl or alkoxycarbonyl substituents in place of the 1-halo substituent by reaction with carbon monoxide and water or an alcohol respectively, in the presence of a palladium II salt: trihydrocarbylphosphine complex type catalyst. |
